IMPROVEMENT IN CARS FOR CARRYINGKPETROLEUM.

Specification forming part of Letters PatentNo. 40,458, (lated November 3, 1&6'3,

To all whom if may concer/z;

Be it known that I, JOHN CLARK, of Canandaigua, in the county of Ontario and State of New York, have inventeda new and useful Improvement in Cars for Carrying Petroleum, &c., in Bulk; and Ido hereby declare that the following is afull, clear, and exact description ofthe same, reference being had to the accompanying drawings, forminga part of this specifir-ation, in which- Figure l represents a longitudinal vertical section of my invention. Fig. 2 is a horizontal section of the same.

Similar letters of reference in both Views indicate corresponding parts.

This invention consists in the application of a tank, of sheet metal or other suitable material, under the platform of an Ordinary railroad-car in such amanner that a large quantity ofpetroleum can be carried in-bulk, and at the same time the car can be used in its ordinary capacity as a package or dirt car.

To enable those skilled in the art to make and use my invention, I will proceed to describe it.

A represents the platform of an ordinary dirt or package car, which rests on a frame, B, supported by two or more trucks, C.

D is a tank, made of sheet metal or other suitable material of sufficient strength for the occasion, and impervious to petroleum. This tank extends throughout the entire length and width of the car under the platform A, which is raised sufficiently high to make room for said tank. The tank itself rests on the frame B, and said frame may be provided with a second platform or bottom, B, to form a strong and substantial support forthe tank. tank) is strengthened by one or morelongit'udinal partitions or bulk-heads, a, and transverse partitions or bulk-heads b, which also divide the interior of said tank into a number Ofcompartments, c, so as to obviate the splashing of y the oil when the car is in motion. The oil is introduced through a cylindrical spout, d, which extends up through the platform A,

It (the and is closed hy a screw-plug, e. This plug is provided with a vent-pipe, f, to allow the gas to escape which rises from the petroleum, particularly when the same is agitated or when a Violent motion is imparted to it.

The platform A is strengthened by two longitudinal timbers, g, attached to its under side near to its edges, and by aseries of transverse timbers, h hf, two of which connect with the ends of the longitudinal timbers g, while the f balance extends from one of said timbers to the other under the platform at suitable intervals. The timbers g hv are supported by planks z', placed edgewise on the frameB of the car, and these planks are of such a height or Width that the timbers g' h h?" clear the upper surface of the tank D. .Standards j, which are firmly secured to the outside of the timbers g 7L* under the platforn1,and which fit into loops k, secured to the outside of the frame C, hold the platform, together with the timbers and planks attached to it, in the proper position.

The tank is filled through the spout d, and it is emptied through a suitable faucet or faucets. Vhen it has been fillled and the spout closed, the platform A can be used for carrying dirt or any other material or goods, precisely as an ordinary platform. The tank does not interfere in any way with the ordinary functions ofthe car, and a quantity of petroleum can thus beKV carried from place to Without incurring the expense of barrels, and perfectly safe from leakage.

What I claim as new, and desire to secure by Letters Patent, is-

The application of a tank, D, under the platform A of a railroad-car, substantially as andfor the purpose specified.

JOHN CLARK.
